This guide is educational information about thyroid health — it is not medical advice, diagnosis, or treatment, and it is not a substitute for care from a qualified doctor or endocrinologist. It does not diagnose, treat, cure, or prevent any condition. Thyroid conditions are diagnosed with blood tests and managed by your doctor; do not start, stop, or change any thyroid medication or dose without medical advice. See your doctor about persistent symptoms such as fatigue, unexplained weight change, or neck swelling, and have any lump or swelling in your neck checked. Seek urgent care for a very rapid or irregular heartbeat, high fever with agitation or confusion, or severe drowsiness; in a medical emergency, call 911.
